Power Distribution Modules (PDMs)

Power Distribution Modules

Cobham's Power Distribution Modules (PDMs) offer the industry's best end-to-end efficiency from the satellite bus (22 - 100V) down to the point of load. The PDMs are a two stage solution that leverage resonant mode control, zero-voltage/zero-current switching, chip on board manufacturing, planar magnetics, proprietary FETs, controllers and drivers to provide greater than 50W of power at 83%+ end-to-end efficiency to your FPGA or ASIC. All of this is accomplished in a very small footprint of ~4in2.

These modules are also radiation hardened to meet 50 krad(Si) TID and SEL immunity up to 80 MeV-cm2/mg.

The PDMs are a family of Input Regulator Modules (IRM) and Isolated Point of Load Modules (iPOL) that together make up a power conversion system. The IRM provides a regulated intermediate voltage to the iPOL which can be set to adjust to load condition by utilizing the adaptive loop feature between the IRM and iPOL. The iPOLs are isolated, unregulated, DC/DC converters that divide down the intermediate bus voltage, provided by the IRM, by a constant k-factor. These PDMs can generate an adjustable output voltage as low as 0.65V to meet the core voltage requirements of the latest FPGAs and ASICs.

Also, these modules are specified to operate from -40°C to +125°C and QML Class L MIL-PRF-38534 qualification is pending. For more information on the PDMs, please email us at info-ams@cobham.com.
